SAMUEL D. KEENE, OF PROVIDENCE, RHODE ISLAND.

C ARDlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 367,914, dated August9, 1887. Application filed October 13, 1886. Serial No 216,128. (Nomodel.)

To all whom it may concern.

' Be it known that I, SAMUEL D. KEENE, a

citizen of the United States, residing atProvideuce, in the county ofProvidence and State of Rhode Island, have invented certain new anduseful Improvements in Carding-Machines; and

I do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to t an attachmentcombining slotted end frames,

separator-bars adjustably secured to said frames, and means for adjustably securing the attachment to the card-frame.

It also consists in the novel device for adjustably securing theseparator --bars to the curved frames, whereby each bar is adapted to beaxially adjusted with relation to the li'ckerin or roll, andindependently of the other bars composing the separator.

It further consists in providing ,the slotted end frames of the saidattachment with a gage or scale, whereby the separator-bars mounted inthe frames are adapted to be accurately spaced, all as will be morefully hereinafter set forth and claimed.

The object of my invention is to provide carding-engines with improvedmeans for extracting motes and other foreign matter from the stapleprior to feeding it to the main cylinder thereof.

In the accompanying sheet of drawings, illustrating the invention,Figure 1 represents a partial vertical transverse sectional view of acotton-carding machine, showing the separator-bars, &c., in positionbelow the licker in or leader-roll; Fig. 2i's a detached plan view ofthe separator. Fig. 3 is an enlarged partial side view of the curved endframe, showing two separator-bars in section adjustably retained inposition therein. .Fig'. 4 is a transverse sectional view of the same,taken on line 0; m. a detached perspective view of one of theclamping-dogs. Fig. 7 isa similar view ofone of the roughened gibsadapted to be used in connection with said dog.' Fig. 8 is an enlargedside view showing the manner of joining the curved end frame to' theshort end frame, secured to the card-frame below the working or cleanerroll; and Fig. 9 is a view silnilarto Fig. 1, the workingroll and shortend frame, however, being omitted, the cotton in this case passing fromthe'feed-rolls to the leader-roll and thence direct to the cardcylinder.

The following is a detailed description of the invention, including themanner of its operation. I will, however, first describe the parts ofthe carding-machine which are common to this class of mechanism, and asrepresented in the drawings.

A, referring thereto in Fig. 1, indicates the card-cylinder covered withcardclothing having wire teeth a and secured to the shaft 5, as usual.

It R designate the fecdrolls, between which the staple is fed to thesaid cylinder A, E being the lickerin or leaderroll, and J indicatingthe working-roll, which latter delivers the staple to the card-cylinder.

L designates a curved and grooved end frame secured (one at each end) bymeans of screws 0 to the main frame F below the working-roll J Theseframes are adapted to receive T- bars B thus forming a separator, alsoas common. On the front end of the frame L is'formed the socket d, intowhich the rear end, (1, of the curved end frame, D,(about to bedescribed,) is adapted to interlock, as shown enlarged in Fig. 8.

D D designate curved end frames, which are adj ustably secured toopposite inner sides of the card-frame F by screws 0. Each frame has aslotted opening, 0, formed in its lower portion, through which the screwpasses. The radius for describing the curvature of the frame is slightlygreater than that for the leader-roll The upper or concave side of theframes D are each provided with a series of grooves,

Fig. 5 is a plan view thereof. Fig. 6 is g, to form a gage, the lower orconvex surface thereof being roughened or corrugated, as at a.

Zindicates a continuous groove formed in the face of the said frame.

H, Fig. 6, designates a dog or clamp having at one end an arm, 2),projecting at right angles therefrom, said arm being drilled at p toreceive a journal, I), of the separator-bars B. The opposite end of thedog H. is drilled and tapped to receive the set'serew Z, the point ofthe latter engaging, when in use, the metal gib 8. (See Figs. 3 and 4.)The said gib is provided with ears .9, which serve to retain it inposition longitudinally, while a lip, 111, formed on the dog, serves toprevent the gib from working out laterally. The upper surface, a, Fig.7, of the gib is concave, and also made corrugated ,to conform,essential] y, to thelower surface, a, of the frame D, before described,and as shown in Fig; 3.

B Bindicate separator-bars, each end thereof being provided with anoffset journal, I), fitted to the hole 1) of the clamp II. (See Fig. 4.)Said bars may be T'shaped or angular in cross section, as desired.

It is obvious that the separator-bars may be, adj ustabl y retained inposition both axially and circumferentially in the curved end frames, D,by means of the clamps I-I, gibs s, and screws Z, just described.

The operation is as follows: The curved frames D D are first secured toopposite sides of the card-frame F by the screws 0, and interlockingwith the short supplemental. frames L, if desired, as shown in Fig. 1. Iprefer in ordinary work and using medium staple to set the forward endof the frames D so that the upper edge of the first bar B just clearsthe leader-roll E, while the rear end of said frames are adjusted so asto carry the adjacent bars about three-quarters of an inch from the saidroll. It is obvious, however, that the adjustment of the framesD shouldbe made with reference both to the kind of staple or fiber c and thequality being used. The separator-bars B should for like reasons beadjusted to the varying conditions of staple and grade.

For the lower grades of cotton, containing a large amount of motes,seeds, and other impurities, the bar sshould be set at quite at angle,so as to form comparatively large openingsZ between them, such axialadjustment being readily accomplished by loosening the screws Z, thenturning said bars to the desired position, and retightening the screws,thejournal p then bearing against the lower surface of the groove Z ofthe frames D, as shown in Figs. 3 and 4-. To facilitate and insure thetrue alignment of the bars, I have introduced the gage r as indicated inFigs. 2, 5, and S.

In Fig. 9 all the bars B are represented as being substantiallyequidistant from the leader-- roll. Now, upon rapidly revolving therolls E J and the main cylinder A, and feeding, say, cotton staplebetween the feed-rolls R, the staple is first taken up by theleader-roll E, from which it is carried to and taken off by theworking-roll J, which in turn delivers it to the card cylinder, asusual. While the staple is thus being rapidly conveyed by the roll Efrom the feed-rolls to the working-roll J, the bars 13 serve tointercept and separate the impurities thrown off by centrifugal forcefrom the cotton and conduct the same through the openings 1 to the flooror a suitable rcceptacle placed beneath.

The dogs H, together with the bars 13, may be readily removed from theframes I) when desired. The latter also may be quickly detached from theframes F and L by first removing the screws 0.

I am aware that attachments provided with bars for separating impuritiesfrom eotton,&c., have been applied to carding-engines prior to mypresent invention. Therefore I do not, broadly, claim such apparatus;but

\Vhat I do claim, and desire to secure by United States Letters Patent,is-- 1. The combination, with the feeding-rolls, leading-roll, andcarding-cylinder, of right and left curved end frames provided withslots, bolts for ad j ustabl y securi n g said frames to the frame ofthe carding-machine below the leading-roll, bars B for intercepting andseparating the motes, &c., from the staple while passing from thefeed-rolls to the carding-cylinder, dogs or clamps having said bars journaled therein, and means for retaining the bars in position afteradjustment, the whole constructed and arranged substantially asdescribed, and for the purpose hereinbefore set forth.

2. The combination, with the curved end frames, D, each having a gageformed in its concave face, and means for securing said frames to acarding-machine, of separator-bars, dogs, as If, in which the bars arejournaled, and screws for adj ustabl y clamping the dogs in position,substantially as described, and for the purpose hereinbefore set forth.
